Hey, Quintin. I think you should reconsider this plan for a few reasons:

The right to download a piece of music for personal use does not equate to a right to redistribute it.

There is no open right to redistribute something that was formerly distributed by someone else but is no long available.

It is important to respect the wishes of the creators of content.

I know that many remixers from a decade ago seem to have disappeared, but this isn't the way to solve the problem. A more positive approach would be to try to track some of them down. I'm sure that many of them would be interested in an opportunity to spotlight their works, but it is still important to ask first. Many in the community would support a concerted effort to accomplish this.

Treating content creators respectfully is critical in the long term. Failing to do that is damaging to your legacy, and once your brand is associated with the file-traders, there is no way to salvage it.
